0:6En efecto, rematado ya su juicio, vino a dar en el más extraño pensamiento que jamás dió loco en el mundo, y fue que le pareciço convenible y necesario, así para el aumento de su honra como para el servicio de su república, hacerse caballero andante, e irse por todo el mundo con sus armas y caballo a buscar las aventuraas y a ejercitarse en todo aquello que él había leído que los cabballeros andantes se ejercitaban, deshaciendo todo género de agravio, y poniéndose en ocasiones y peligros donde, acabándolos, cobrase eterno nombre y fama.
In short, his wits being quite gone, he hit upon the strangest notion that ever madman in this world hit upon, and that was that he fancied it was right and requisite, as well for the support of his own honor as for the service of his country, that he should make a knight-errant of himself, roaming the world over in full armor and on horseback in quest of adventures, and putting in practice himself all that he had read of as being the usual practices of knights-errant; righting every kind of wrong, and exposing himself to peril and danger from which, in the issue, he was to reap eternal renown and fame.
